Teachers’ perceptions of their most significant change: source,impact, and process     

John E. Henning  Linda J. Rice  Danielle E. Dani  Ginger Weade  Timothy McKeny 《Teacher Development》2017,21(3):388-403

The purpose of the study was to examine the differences among significant changes in the practice of individual teachers. Seventeen US teachers were interviewed about the most successful change in their teaching career. The differences in teacher change were based primarily on the source and impact of the change. The sources of change were divided into two categories: other-initiated or self-initiated. The level of impact was determined in three ways: by whether teachers described a new practice, a new direction, or a change in their beliefs. By organizing according to both the source and impact of the change, four types of change were identified: Response to School Initiatives, Professional Development Initiatives, Student-Centered Changes, and Self-Designed Changes. Self-Designed changes were further distinguished based on the time required for the change process. Implications for developing new strategies to foster teacher development are discussed.  相似文献   

Caregiver perceptions of sexual abuse and its effect on management after a disclosure     

Walker-Descartes I  Sealy YM  Laraque D  Rojas M 《Child abuse & neglect》2011,35(6):437-447

Objective

The aim of the study was to examine caregiver management strategies for child sexual abuse (CSA) when presented with hypothetical scenarios that vary in physical invasiveness.

Methods

One hundred fifty three caregivers were given 3 scenarios of CSA with 7 management strategies presented in the 21-item Taking Action Strategies (TAS) scale. Caregivers were asked to rate strategies according to their willingness to carry out each action with rating of 5 = greater likelihood of carrying out the action specified while a rating of 1 = a lower likelihood of carrying out that action. CSA scenarios included exposure to pornography/masturbation, fondling, and penetration while management strategies including fighting the accused, blaming the child, and outreaching to the authorities. Repeated measures ANOVA was used to compare mean TAS scores for the management strategies across CSA scenarios.

Results

The difference between TAS scores across the abuse scenarios was statistically significant (p < .001). Mean TAS scores reflected greater preference for taking action if the abusive act was perceived as more physically intrusive (exposure to pornography/masturbation-TAS 3.5, fondling-TAS 3.7, penetration-TAS 3.8). Caregivers reported being less willing to handle a disclosure of CSA without outreach (TAS 2.5 and 2.0 for fighting and blaming the child, respectively) and more willing to manage a disclosure with outreach to authorities (TAS 3.8, 4.5, and 4.7 for outreaching to Child Protective Services [CPS], to the child's healthcare provider and police, respectively). A predictor of caregiver outreach to authorities identified was the caregiver having past interactions with CPS.

Conclusion

Perception of the physical invasiveness of CSA and demographic factors can impact caregiver management strategies after a disclosure.

Practice implications

Results suggest that several factors influence caregiver management of sexual abuse. These factors warrant further study, as they are potential contributors to declining trends in CSA cases observed. Other implications include the need for educational efforts targeting caregivers. These interventions should focus on dispelling myths about the perceived physical invasiveness of CSA. These perceptions should not mitigate a caregiver's decision to involve the authorities in their management after a disclosure. Lastly, despite criticisms of the child protective systems, caregivers with past encounters with CPS view these related agencies as valuable resources.  相似文献   

Differential susceptibility to adolescent externalizing trajectories: examining the interplay between CHRM2 and peer group antisocial behavior     

Latendresse SJ  Bates JE  Goodnight JA  Lansford JE  Budde JP  Goate A  Dodge KA  Pettit GS  Dick DM 《Child development》2011,82(6):1797-1814

The present study characterized prototypical patterns of development in self-reported externalizing behavior, between 12 and 22 years of age, within a community sample of 452 genotyped individuals. A Caucasian subset (n = 378) was then examined to determine whether their probabilities of displaying discrete trajectories were differentially associated with CHRM2, a gene implicated in self-regulatory processes across a range of externalizing behaviors, and if affiliating with antisocial peers moderated these associations. Findings indicate that relative to a normative "lower risk" externalizing trajectory, likelihood of membership in two "higher risk" trajectories increased with each additional copy of the minor allelic variant at CHRM2, and that this association was exacerbated among those exposed to higher levels of peer group antisocial behavior.  相似文献

A rapid evidence‐based service by librarians provided information to answer primary care clinical questions     

Jessie McGowan  William Hogg  Tamara Rader  Doug Salzwedel  Danielle Worster  Elise Cogo  Margo Rowan 《Health information and libraries journal》2010,27(1):11-21

Background: A librarian consultation service was offered to 88 primary care clinicians during office hours. This included a streamlined evidence‐based process to answer questions in fewer than 20 min. This included a contact centre accessed through a Web‐based platform and using hand‐held devices and computers with Web access. Librarians were given technical training in evidence‐based medicine, including how to summarise evidence. Objectives: To describe the process and lessons learned from developing and operating a rapid response librarian consultation service for primary care clinicians. Methods: Evaluation included librarian interviews and a clinician exit satisfaction survey. Results: Clinicians were positive about its impact on their clinical practice and decision making. The project revealed some important ‘lessons learned’ in the clinical use of hand‐held devices, knowledge translation and training for clinicians and librarians. Conclusions: The Just‐in‐Time Librarian Consultation Service showed that it was possible to provide evidence‐based answers to clinical questions in 15 min or less. The project overcame a number of barriers using innovative solutions. There are many opportunities to build on this experience for future joint projects of librarians and healthcare providers.  相似文献

Accelerometer and self-reported measures of sedentary behaviour and associations with adiposity in UK youth     

Robert J. Noonan  Danielle Christian  Lynne M. Boddy  Pedro F. Saint-Maurice  Gregory J. Welk  Paul R. Hibbing 《Journal of sports sciences》2019,37(16):1919-1925

This study used accelerometer and self-report measures of overall sedentary time (ST) and screen time behaviours to examine their respective associations with adiposity among UK youth. Participants (Year groups 5, 8, and 10; n=292, 148 girls) wore the SenseWear Armband Mini accelerometer for eight days and completed the Youth Activity Profile, an online report tool designed to estimate physical activity and ST.Stature, body mass and waist circumference were measured to classify adiposity outcomes (overweight/obese and central obesity). One-way between groups ANOVA and adjusted linear, logistic and multinomial logistic regression analyses were conducted. There was a significant main effect of age on total ST across the whole week (F(2, 289)=41.64, p≤0.001). ST increased monotonically across Year 5 (581.09±107.81 min·dˉ¹), 8 (671.96±112.59 min·dˉ¹) and 10 (725.80±115.20 min·dˉ¹), and all pairwise comparisons were significant at p≤0.001. A steep age-related gradient to mobile phone use was present (p≤0.001). ST was positively associated with adiposity outcomes independent of moderate-to-vigorous intensity physical activity (MVPA; p≤0.001). Engaging in >3 hours of video gaming daily was positively associated with central obesity (OR=2.12, p≤0.05) but not after adjustment for MVPA. Results further demonstrate the importance of reducing overall ST to maintain healthy weight status among UK youth.  相似文献   

Levels of social complexity and dimensions of peer experiences in youth sport   总被引：1，自引：0，他引：1  

Holt NL  Black DE  Tamminen KA  Fox KR  Mandigo JL 《运动与训练心理学杂志》2008,30(4):411-431

We assessed young adolescent female soccer players' perceptions of their peer group experiences. Data were collected via interviews with 34 girls from two youth soccer teams (M age = 13.0 years). Following inductive discovery analysis, data were subjected to an interpretive theoretical analysis guided by a model of peer experiences (Rubin, Bukowski, & Parker, 2006). Five categories of peer experiences were identified across three levels of social complexity. At the interaction level players integrated new members into the team and learned to interact with different types of people. At the relationship level players learned about managing peer conflict. At the group level a structure of leadership emerged and players learned to work together. Findings demonstrated interfaces between peer interactions, relationships, and group processes while also simplifying some apparently complex systems that characterized peer experiences on the teams studied.  相似文献   

Developing tests of impaired coordination for Paralympic classification: normative values and test–retest reliability     

Mark J. Connick  Emma Beckman  Rebecca Deuble  Sean M. Tweedy 《Sports Engineering》2016,19(3):147-154

Current methods of assessing coordination in Paralympic classification are non-instrumented and are based on ordinal scales of measurement and therefore impede the development of evidence-based methods of classification. This paper describes an instrumented battery of tests that measure impaired coordination in a way that will permit evidence-based classification. Test–retest reliability and normative values for each of the tests are reported. Twenty participants visited the laboratory on two occasions, each time completing 11 tests: three running-specific, lower-limb reciprocal tapping tests (yielding five outcome measures); four throwing-specific, upper-limb discrete tapping tests (yielding four outcome measures); and four wheelchair-specific, upper-limb reciprocal tapping tests yielding seven outcome measures. Reliability was evaluated using Intra-class Correlation Coefficients (ICCs), Standard Error of Measurement, Limits of Agreement and Paired t-tests. ICCs for fourteen of the 16 outcome measures were excellent (ICC ≥ 0.80), although systematic bias was evident in two of these—a unilateral, running-specific lower-limb tests on the non-dominant side, and a unilateral wheelchair-specific upper limb test on the dominant side. ICCs for two tests—a bilateral wheelchair-specific upper limb test (0.74), and a unilateral wheelchair-specific upper limb test on the non-dominant side (0.54)—were good and fair respectively. Results indicate that 12 of the measures evaluated have measurement properties that will facilitate the development of evidence-based methods of Paralympic classification in athletics. Positional adjustment and increased familiarization may improve reliability in the other four. Studies evaluating reliability of this test battery in people with coordination impairments are warranted.  相似文献   

The ontogeny of phonological categories and the primacy of lexical learning in linguistic development     

Beckman ME  Edwards J 《Child development》2000,71(1):240-249

In this paper, we draw on recent developments in several areas of cognitive science that suggest that the lexicon is at the core of grammatical generalizations at several different levels of representation. Evidence comes from many sources, including recent studies on language processing in adults and on language acquisition in children. Phonological behavior is influenced very early by pattern frequency in the lexicon of the ambient language, and we propose that phonological acquisition might provide the initial bootstrapping into grammatical generalization in general. The phonological categories over which pattern frequencies are calculated, however, are neither transparently available in the audiovisual signal nor deterministically fixed by the physiological and perceptual capacities of the species. Therefore, we need several age-appropriate models of how the lexicon can influence a child's interactions with the ambient language over the course of phonological acquisition.  相似文献
